Shoulder isokinetic dynamometer A8-2

anklehipknee

Comprehensive multi-joint system for evaluation and training of isokinetic, isometric, isotonic and continuous passive programs across shoulder, elbow, wrist, hip, knee and ankle.

Product introduction
The AI A8-2 provides clinical-grade assessment and progressive training protocols for six major joints. Test and training sessions generate numerical data and graphs that can be reviewed, exported and printed as clinical or research reports. Multiple modes support rehabilitation from early passive motion to advanced strength conditioning.

Definition of isokinetic
Isokinetic motion: movement at a preset constant angular velocity with variable resistance. The device maintains the set speed while resistance varies with user force, enabling torque measurement without acceleration.

Key characteristics

• Accurate strength testing: measures peak torque and torque across joint angles to assess bilateral differences and agonist/antagonist ratios.
• Safe, adaptive training: applies controlled resistance at each joint angle and reduces load if subject strength decreases.
• Data management: records, analyzes and compares successive tests; supports report generation and printing.
• Dual range-of-motion protection: mechanical and software limits to ensure safe testing/training boundaries.

Indications

• Motor dysfunction from sports injuries, post‑operative orthopedics, conservative treatments, nerve lesions and similar causes.

Contraindications

• High fracture risk, acute disease phase, severe pain or marked joint mobility restriction.

Clinical applications

• Orthopedics, neurology, rehabilitation, sports medicine and functional research.

Orthopedic rehabilitation pathway

• Continuous passive motion: maintain/restore ROM and reduce contractures/adhesions.
• Isometric training: counteract disuse and initiate strength recovery.
• Isokinetic training: increase muscle strength and optimize fiber recruitment.
• Isotonic training: improve neuromuscular control.
